Description

A fixed tower crane foundation pre-embedded anchor bolt positioning tool

technical field

The utility model relates to a positioning tool for pre-embedded foundation bolts of a fixed tower crane foundation, which belongs to the technical field of building construction.

Background technique

Since the tower crane is a necessary vertical transportation construction machine for building construction at present, there are many manufacturers and specifications, and the design forms of tower crane foundations of different manufacturers are also different. Some tower crane foundations are designed to be fixed, that is, the tower crane foundation section and concrete The foundation is connected by pre-embedded anchor bolts. Therefore, the positioning of the anchor bolts will directly affect the installation quality and effect of the tower crane. At present, the commonly used positioning method is to connect the anchor bolts into a whole in the form of steel bar welding, but this There are also defects in the method. It is difficult to guarantee the verticality, flatness and plane position accuracy of the anchor bolts. Therefore, it is necessary to find a positioning tool for anchor bolts that meets the above requirements.

Contents of the invention

The technical problem to be solved by the utility model is to provide a fixed tower crane foundation pre-buried anchor bolt positioning tool, which not only controls the plane position accurately, and the vertical flatness meets the requirements, but also can be made from materials on the construction site, easy to use, and reusable. .

The purpose of this utility model is achieved in that:

A fixed tower crane foundation pre-embedded anchor bolt positioning tool includes a positioning frame, a fixing frame and a reinforcing frame.

The locating frame is provided with an upper locating plate, a lower locating plate and a support member, the lower locating plate is longer than the upper locating length in the direction of the fixed frame area, and the supporting member is vertically fixed on the four corners of the upper locating plate and the lower locating plate.

The four equilateral angle steels of the fixed frame are connected and fixed with the positioning frame by bolts.

The four equilateral angle steels of the reinforcing frame are connected and fixed with the fixing frame by bolts.

Both the fixing frame and the reinforcing frame can be disassembled and assembled with tools.

Detailed ways

Below in conjunction with example the utility model is further described.

The utility model, as shown in Figure 1, is a fixed tower crane foundation embedded anchor bolt positioning tool, comprising a positioning frame (1), a fixing frame (2) and a reinforcing frame (3). The positioning frame (1) is provided with an upper positioning plate (6), a lower positioning plate (8) and a support (7), and the lower positioning plate (8) is in the fixed frame (2) area direction than the upper positioning plate (6) The length increases, and the support (7) is vertically fixed on the four corners of the upper positioning plate (6) and the lower positioning plate (8). The four equilateral angle steels of the fixed frame (2) are connected and fixed with the positioning frame (1) by bolts (4). The four equilateral angle steels of the reinforcing frame (3) are connected and fixed with the fixing frame (2) through bolts (5). Both the fixing frame (2) and the reinforcing frame (3) can be disassembled and assembled with tools.

On-site production material selection: the upper positioning plate and the lower positioning plate of the positioning frame are made of 10mm thick steel plate, the support is made of 16mm diameter rebar, the upper positioning plate and the lower positioning plate are welded and fixed with the support; the fixing frame is made of Made of 90×90×10 equilateral angle steel; the reinforcing frame adopts Made of 80×80×10 equilateral angle steel.

Construction technology: ① Determine the size of the upper and lower positioning plates, the height of the support, the length of the angle steel of the fixed frame and the reinforcing frame according to the position and size of the tower crane's pre-embedded anchor bolts, and make the positioning frame; ② Pop out the tower on the foundation of the tower crane The axis of the machine center and the positioning line of the anchor bolts; ③Fix the fixing frame with the bolts of the positioning frame; ④Fix the reinforcement frame with the bolts of the fixing frame; The fixing frame, reinforcing frame and anchor bolts are placed on the foundation steel bars of the tower crane, and correspond to the positioning line; ⑦After the positioning is accurate, the anchor bolts are welded and fixed to the foundation steel bars with steel bars to prevent the entire frame from moving; ⑧Concrete pouring completes the strength If the reinforcement frame, fixed frame and positioning frame are dismantled according to the requirements, the next tower crane foundation construction can be started.

This tool ensures the verticality of the anchor bolts through the upper positioning plate and the lower positioning plate of the positioning frame, and ensures the flatness of the anchor bolts and the tower crane chassis through the fixing frame and the reinforcing frame. Accuracy effectively solves the problem of inaccurate positioning of the pre-embedded anchor bolts of the fixed tower crane foundation at the construction site. This tool can be made from materials at the construction site, easy to install and use, and can be reused.
